UND Assay
Evidence on MCP servers before you install: publisher, source, provenance, advisories, changes.
¿Debería usar esto?
Calidad y seguridad
Basado en el análisis automatizado de las definiciones de herramientas y el cumplimiento del protocolo.
Costo de contexto
Este es el número aproximado de tokens que se consumen cada vez que las herramientas del servidor se cargan en el contexto de un modelo. Los recuentos más altos reducen la atención disponible para otras tareas.

Herramientas (8)
🟢check_before_install(identifier)
Evidence summary for an MCP server before you install or connect it: publisher identity level, provenance, known vulnerabilities, install scripts, maintenance, open warnings, checks that could not run, and recent changes. No warnings is NOT a safety guarantee.
Esquema de entrada
{
"type": "object",
"properties": {
"identifier": {
"type": "string",
"description": "MCP server name (e.g. io.github.github/github-mcp-server), catalog id, or GitHub repository URL"
}
},
"required": [
"identifier"
],
"additionalProperties": false
}🟢get_setup(identifier)
One stable answer (schema_version 1) for connecting an MCP server: its validated remote URL and transport, packages, copy-paste setup for Claude Code and JSON configs, warnings by severity, checks that could not run, and contradicted claims. auth is null until Assay has checked the sign-in metadata of the server. Never a safety rating.

"additionalProperties": false
}🟢resolve_identifier(identifier)
Resolve an MCP server name, catalog id or GitHub repository URL to the real registry entry. If there is no exact match, returns the closest real names so look-alikes and invented names can be caught. No account needed.

}🟢search_tools(query, official_only, limit)
Search cataloged MCP servers by keywords. Returns classification (verified_publisher = the publisher proved control of a domain or verified GitHub org, NOT that a company named in the tool made it / community / not_analyzed), identity level and warning counts.

}🟢get_tool(tool_id)
Every assertion for a tool with its state (VERIFIED, CLAIMED, CONTRADICTED, STALE, UNKNOWN), reason, check and evidence records.

How a publisher is identified across ecosystems (MCP namespace, domain, GitHub, packages) and the state of each link.

"publisher_key": {
"type": "string"

A single assertion of a tool (by field name) with the evidence records behind it: URL, fetch time, SHA-256.
